    Synthesis of 1-substituted 2-azaspiro[4.5]deca-6,9-diene-8-ones and 2-azaspiro[4.5]deca-1,6,9-triene-8-ones by a three-component condensation of 1,2,3-, 1,2,4- or 1,3,5-trimethoxybenzene with isobutyric aldehyde and nitriles [Text] / V.

Аннотация: A three-component condensation of 1,2,3- or 1,2,4-trimethoxybenzene with isobutyric aldehyde and alkyl cyanoacetates in the presence of sulfuric acid resulted in the formation of substituted 2-azaspiro[4.5]deca-6,9-diene-8-ones. The same reaction of aromatic nitriles yielded 2-azaspiro[4.5]deca-1,6,9-triene-8-ones; in the case of 1,2,3-trimethoxybenzene corresponding Ritter amides were also observed. The condensation of 1,3,5-trimethoxybenzene with isobutyric aldehyde and alkyl cyanoacetates provided the compounds of the formal Knoevenagel condensation

ZINC ENOLATES -- CARBOXAMIDES -- E-POSITION
Аннотация: Zinc enolates obtained from ethyl 2,2-dialkyl-4,4-dibromo-3-oxobutanoates and zinc react with N-substituted 2-oxochromen-3-carboxamides forming ethyl 3-(1a-(R3-carbamoyl)-2-oxo-1a,7b-dihydrocyclopropa[c]chromen-1-yl)-2,2-dialkyl-3-oxopropanoate isomer with a Z-position of methine hydrogens. Zinc enolates prepared from alkyl 2,2-dialkyl-4,4-dibromo-3-oxopentanoates and-hexanoates and zinc react with N-substituted 2-oxochromen-3-carboxamides to give rise to esters of 3-(1-alkyl-1a-(R3-carbamoyl)-2-oxo-1a,7b-dihydrocyclopropa-[c]chromen-1-yl)-2,2-dialkyl-3-oxopropanoic acid as isomers with the E-position of the methine proton and the alkyl substituent. The reaction carried out in the presence of small quantities of THF and HMPA leads to the formation of 9c-alkyl-2-R3-9b,9c-dihydro-5-oxa-2-azacyclopenta[2,3]-cyclopropa[1,2-a]naphthalene-1,3,4-triones. Zinc enolates from alkyl 2,2-dialkyl-4,4-dibromo-3-oxopentanoates and-hexanoates and zinc with the secondary amides of 2-oxochromen-3-carboxylic acid form alkyl 3-(2-oxo-1a-(piperidinocarbonyl)-and 3-(6-R1-1a-(morpholinocarbonyl)-2-oxo-1a,7b-dihydrocyclopropa[c]chromen-1-yl)-2,2-R2,R2-3-oxopropanoates as single geometrical isomers

Аннотация: Reactions of chromones with methyl ketoximes in the presence of lithium diisopropylamide follow the nucleophilic 1,2-addition mechanism to give spiro[4H-chromene-4,5?-isoxazolines] in good yields. The isoxazoline ring in spiro[4H-chromene-4,5?-isoxazolines] undergoes opening under the action of conc. H2SO4, yielding ?,?-unsaturated oximes. Their nitrosation and bromination lead to the corresponding spiroisoxazolines, while the Beckmann rearrangement, to ?,?-unsaturated amides. The latter are also formed directly from spiro[4H-chromene-4,5?-isoxazolines] under the action of PCl5. N-Substituted acetophenone hydrazones in the presence of lithium diisopropylamide react at the C(4) atom of 2-trifluoromethylchromone, while acetophenone anil under the same conditions, at the C(2) atom

    Nonenzymatic Acylative Kinetic Resolution of Racemic Amines and Related Compounds / V. P. Krasnov, D. A. Gruzdev, G. L. Levit // European Journal of Organic Chemistry. - 2012. - Vol.2012, №8. - С. 1471-1493. - Bibliogr. : p. 1491-1493 (76 ref.)

KINETIC RESOLUTION -- ACYLATION -- AMINES -- AMIDES
Аннотация: Acylative kinetic resolution of racemic amines occupies a highly important place among the methods for preparation of enantio enriched or pure amines. Nonenzymatic acylative kinetic resolution is usually carried out in the presence of chiral acyl-transfer catalysts or under the action of chiral enantio- or diastereoselective resolving agents. Recently, this line of investigations has been rapidly developed and very interesting results of design and synthetic application of both new catalysts and chiral acylating agents have been obtained. This microreview summarizes the recent advances in this area.

6-CHLOROPURINE -- HETEROCYCLIC AMINES -- ANTIVIRAL ACTIVITY -- INFLUENZA A AND B VIRUSES
Аннотация: A number of novel amides were synthesized by coupling of 6-[(9H-purin-6-yl)amino]hexanoic acid to heterocyclic amines. The antiviral activity of the obtained compounds, as well as of purine conjugates in which 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine is linked to position 6 of purine through a fragment of ɷ-amino acids with varying lengths of polymethylene chains against influenza A and B viruses was studied in vitro. Purine derivatives have been shown to have moderate activity against influenza A (H1N1) virus. The antiinfluenza activity and cytotoxicity of conjugates with 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine depend on the length of the linker fragment.
